Answer:
A circle when divided into equal parts, it has two semi circles.
➡ We know that, circumference Or perimeter of a circle is 2πr.
✒so, circumference of a semi- circle =( π+2) r
Now, according to the given question
Perimeter of the semi circle with radius 7cm
=>( π+2) r
=>(22/7+2) 14
=>36/7×14
=>72cm (ans.)
